WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 311,133, dated January 20, 1885.

Appication filed December 6, 18H5. (No model.)

To all whom t muy concern,.-

Be it known that I, JOHN M. LocKHART, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new` and useful Improvements in Washing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the anneXed drawings, making a part of this speciiication, and to the letters and figures of reference marked thereon.

Figure I of the drawings is a side elevation of my invention, partly in section; and Fig. 2, an under side plan view of the outer tub, showing the position of the internallytoothed gear and pinion wheels.

Thepresent invention has relation to that class of washing-machines in which are employed a tub or outer cylinder provided with a ribbed or corrugated inner surface, and a rubber centrally located therein, each being given by suitable driving mechanism a inotion in opposite directions to thoroughly wash the clothes placed between 'the tub or cylinder and rubber. l

It is the object of the invention to improve the construction of the above class of washing-machines, whereby the necessity of removing the clothes from the machine to rinse them is entirely removed.

The above object I attain by constructing the rubber so that it will serve as a tub or receptacle to 'hold the rinsing-water and clothes after being washed, as will be hereinafter described and claimed.

In the drawings, A represents a suitable stand or frame, in which is journaled a central shaft, B, extending` up through an arm or bearing, a. its lower end, is a beveled gear-Wheel, O, meshing with a similar wheel, D. communieating with suitable crank mechanism, E, supported by standards b c. Secured to the shaft immediately above the arm or bearing a is a pinion-wheel, d, which meshes with another pinion, e, having its bearing in the arm a, this latter pinion in turn meshing with an internally-toothed gear-wheel, f, secured upon the under side of an outer tub or receptacle, F. This tub or receptacle is loosely arranged upon the shaft B, which is extended up through its center, and to the end of which is Secured to this shaft B, near.

fixed an inner tub or receptacle, G, constituting the rubber, which is so constructed that the diameter of its lower portion will be nearly equal to that of the outer one, while its upper portion will be considerably smaller, thus' forming a wedge-shaped space between the two, into which the clothes and water for washing are placed, the outer tub or receptacle being ribbed or corrugated upon its interior face, and the inner one upon its exterior, a suitable cover, H, preventing the heat and steam from escaping during the operation of washing. The tubs or receptacles being operated so as to revolve in opposite directions by means of the mechanism already described, the clothes in the wedge-shaped space are carried rapidly through the water and tightly pressed between the faces of said tubs or receptacles, this pressure increasing as the clotheswork down toward the point of the wedge, thereby causing the removal of the dirt without rubbing. It will be noticed that between the bottoms of the tubs or receptacles there is a space, g, which serves as a rei ceptacle or collector for the dirt when pressed out of the clothes. The tub or receptacle G serves to contain the rinsing-water, and thereby admits of the entire operation of washing and rinsing being performed without the removal of the clothes from the machine, thereby facilitating the work and effecting a saving in time and labor.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A washing-machine consist-ing of two tubs or receptacles, one contained within the other, daring or tapering in opposite directions, and provided with mechanism, substantially as described, for imparting to them a motion in opposite directions, the inner one of said tubs or receptacles serving both as a rubber and a receptacle for containing the rinsing-water and clothes, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN M. LOCKHART.
